Thermal Behaviour:

Fuses at 3 to a black magnetic globule.

Notes:

Slowly and completely soluble in HCl and H2SO4. No reaction to HNO3, FeCl3, KOH, HgCl2, H2O2. The HCl solution gives a strong borate reaction with tumeric paper.

Health Risks:

No information on health risks for this material has been entered into the database. You should always treat mineral specimens with care.
